High levels of saturated fat can adversely affect heart health by raising levels of LDL cholesterol, often referred to as "bad" cholesterol. Elevated LDL cholesterol contributes to the buildup of plaque in arterial walls, increasing the risk of atherosclerosis, heart disease, and stroke. It is recommended to limit saturated fat intake by choosing lean meats, opting for plant-based oils, and consuming low-fat dairy products. Instead of saturated fats, incorporating healthier fats, such as monounsaturated and polyunsaturated fats, is essential for promoting cardiovascular health and overall well-being.
